DOVER, N.H. — Before Christopher Ramos got off the witness stand Wednesday morning, public defender Joachim Barth asked him a few more questions about his motivation for making statements to investigators in the Seth Mazzaglia murder trial.

Ramos is a registered sex offender who was in jail with Mazzaglia after he was arrested for the Oct. 9, 2012 murder of 19-year-old University of New Hampshire student Elizabeth "Lizzi" Marriott. He claimed to have a jailhouse conversation with Mazzaglia about the night of the murder.

Earlier, Barth insinuated that the testimony Ramos was providing in court lessened his plea deal for failing to register as a child sex offender.

Ramos said he was actually over-sentenced after making the arrangement and he had to appeal the sentence.

"Were you afraid she would do it again when you talked with your attorney?" Barth asked.

"They both did it," Ramos replied.

When asked what he meant, Ramos answered, "I am talking about somebody dying."

Barth said Ramos told investigators at the time that Mazzaglia would not tell him all of the details of Marriott's death, just that he blacked out and he was on top of her. McDonough was "at the head."

"You described to investigators that he wouldn't tell you the details and you wouldn't press for the details of exactly how she died?" Barth asked.

"What he told me was enough for me," Ramos replied.

Ramos repeatedly said to Barth that he told Investigators what he knew because he had done so much wrong in his life, he decided to do the right thing once he found out about the crime.

Ramos, who is a self-described "veteran" of the jail system, has been in and out of legal trouble for 26 years. He is being held at Valley Street Jail in Manchester for failure to report as a sex offender.

Ramos, who is a child sex offender, will be on the registry until 2067, Barth said.

DOVER — A man from Florida who has been in the jail system for 26 years and will have to register as a sex offender until 2067 was the first witness to testify Wednesday in the Seth Mazzaglia murder trial at Stafford County Superior Court.

Christopher Ramos, who was led into the courtroom in an orange suit and shackles, told Assistant Attorney Geoffrey Ward that he did not want to be on the witness stand but eventually testified that Mazzaglia told him over a period of time when they were in prison together about the night Elizabeth "Lizzi" Marriott died.

Ramos said Mazzaglia claimed to have blacked out on the night of Oct. 9, 2012. When he regained consciousness in his Sawyer Mill Apartment, he was having sex with the 19-year-old Marriott and his live-in girlfriend Kathryn "Kat" McDonough "was at her head."

Ramos said Mazzaglia never told him what McDonough was doing.

Ramos said when he took the stand that he didn't want to testify because he feared for his safety in prison. "It puts me in a bad situation," he said.

Ramos is being held at Valley Street Jail in Manchester for failing to report as a sex offender. He was being held in the medical unit at Strafford County House of Corrections in the fall of 2012. At that time, Ramos was a being held for failure to register.

Public defender Joachim Barth quickly cut to the chase during his cross-examination of Ramos. He asked Ramos why he was held in the Dover jail on federal charges.

Eventually, Barth asked Ramos if he was in jail at the same time as Mazzaglia because he failed to register as a sex offender against children.

"I thought that couldn't be brought up," Ramos said.

After an objection and a bench conference Judge Steven Houran told the jurors to pretend Barth's question was never asked.
